IMPROVEMENT IN THE MODES OF LUBRICATING JOURNALS.-

Specification forming part of Letters Patent No. 119,288, datedSeptember 26, 1871 antedated September 15, 1871.

To all whom it may concern:

Be. it known that I, STEPHEN UsTIcK, of the city of Philadelphia andState of -Pennsylvania, have invented an improvement in lubricating thejournals of shafts or a continuous line of shafts, of which thefollowing is a specification:

The nature of my invention consists in the connection of a tube or aline of tubes with the oil- `chamber in the pillowblocks or lowerbearings scription thereof.

In the accompanying drawing', which makes a part of this specification,Figure l is aplan view of a shaft, A, the bearings B, oil-reservoir F,and tubes E. Fig. 2 is a side elevation ofthe same. l Like letters inall the iigures indicate the same parts.

` A is a horizontal shaft. B B are pillow-blocks of the same. C G arethe journal-caps. D D are the oil-chan1bers in the pillow-blocks B B. EE are tubes in connection with said oil-chambers.

F is an oil-reservoir for supplying the oil to the chambers D.

a through small openings leading thereto' from v the chambers or throughiibrous materials in larger openings. The reservoir F may be dispensedwith by making one or more of the chambers D of sufficient capacity tohold the requisite supply of oil. When a shaft is provided with a pulleyor pulleys the tube or tubes E should be bent to turn around the same,as illustrated by dotted lines in Fig. 2.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination and arrangement of the oiltubes E with the chambersD ofthe pillow-blocks B, substantially in the manner and for the purposeabove set forth.

In testimony that the above is my invention I have hereunto set my handand afixed my seal y this 19th day of November, 1870.
